What is a Catch-All E-Mail Account?

A “catch-all” e-mail account receives e-mails addressed to undefined or nonexistent users. For example, if an e-mail is addressed to “suhail@yourdomain.com” but the username “suhail” does not exist on that domain, the email is automatically routed to the catch-all account.

In order to run mailyoulike your mail server must support catch all account .
Please refer to the software documentation of your mail server for more information.
